Difference between Synodontis eupterus and ansorgii?

[Mitchell The Monster]

Been getting into catfish recently and was doing some reaserch and now confused on whether I own an eupterus or ansorgii. I love the goof ball either way but would like to know. So, what is the difference between to two species?

Will add one or two more pictures tonight. That is the only picture of mine I have saved on my computer atm. What do you guys think he is?

A hard one for me. Looks closer to eupterus to my eye than ansorgii https://www.planetcatfish.com/common/species.php?species_id=1388 but I'd post on Planet Catfish to be more sure.

Yeah, I was looking the species profiles for both on planetcatfish and that is what made me wonder. I will make an account and ask over too and report back.
